特定の投票以上の投稿を選択するにはどうすればよいですか？

Question

私のテーブル構造：

// posts 
+----+----------------------------------------+-----------+ 
| Id |     body     | user_id | 
+----+----------------------------------------+-----------+ 
| 1 | content1        | 2   | 
| 2 | content2        | 9   | 
| 3 | content3        | 6   | 
| 4 | content4        | 4   | 
| 5 | content5        | 2   | 
| 6 | content6        | 8   | 
| 7 | content7        | 4   | 
| 8 | content8        | 2   | 
+----+----------------------------------------+-----------+ 

// votes 
+----+---------+-------+ 
| id | post_id | value | 
+----+---------+-------+ 
| 1 | 2  | 1 | 
| 2 | 3  | -1 | 
| 3 | 2  | 1 | 
| 4 | 8  | -1 | 
| 5 | 1  | 1 | 
| 6 | 8  | 1 | 
| 7 | 2  | -1 | 
| 8 | 8  | -1 | 
| 9 | 2  | 1 | 
+----+---------+-------+ 

私は1投票合計スコア以上のものを持って記事を選択する必要があります。これは期待される出力です：

+----+----------------------------------------+-----------+-------------+ 
| Id |     body     | user_id | total_votes | 
+----+----------------------------------------+-----------+-------------+ 
| 2 | content2        | 9   | 2   | 
+----+----------------------------------------+-----------+-------------+ 

どうすればいいですか？

create table qanda 
( id int not null, 
    body varchar(100) not null, 
    user_id int not null 
); 
insert qanda values 
(1,'a',2), 
(2,'a',9), 
(3,'a',6), 
(4,'a',4), 
(5,'a',2), 
(6,'a',8), 
(7,'a',2), 
(8,'a',2); 

create table votes 
( id int not null, 
    post_id int not null, 
    value int not null 
); 
insert votes values 
(1,2,1), 
(2,3,-1), 
(3,2,1), 
(4,8,-1), 
(5,1,1), 
(6,8,1), 
(7,2,-1), 
(8,8,-1), 
(9,2,1);

select q.id,q.body,q.user_id,sum(v.value) as votes 
from qanda q 
join votes v 
on v.post_id=q.id 
group by q.id,q.body,q.user_id 
having votes>1;
